Emotional sensitivity differs from one person to another, i.e. people take things differently and if it's not a big deal for you, it doesn't mean it couldn't be a big deal for someone else. Even if it won't be so important for them in 10 minutes, it is now. So try to be supportive and understanding, but don't take it to hard.
It is much better than saying "I know how you feel" if you really don't as this person seems too emotional for you. Of course, you won't understand them totally, as we all see things in a different way, but they will be happy to know that you are trying to understand their emotions.
If someone reacts too emotional, it is not because of the things you do, it is just in the nature of that person. If you get angry or confused because of their emotions, they will not be able to communicate openly and to act honestly with you, as they will need to control their emotions all the time. And it's not that simple. So better just take it easy and see how differently and colourful some people take this world.
If you communicate with someone who has too many emotions there is no need to say about it. These people know their nature and it isn't easy for them at all. So if you remind them about it, nothing will change, they still will be too emotional.
There is always a feeling behind any emotion. If you see someone is full of emotions again, just ask them, what they feel. If it's a happy feeling, you can enjoy it together. If it's something bad, you can try to make it easier by being supportive and interested.
If you see someone crying or overreacting to something, it is natural and kind wanting to help somehow. But you need to remember that it isn't so easy to help emotions of a person who is too emotional. Just give them some time and be near.
If someone is too emotional, you can get upset about their reactions to your actions. You need to relax and remember that they react on everything harder than you do, so their emotions to your actions are higher, too. You can't control them, so just ask about the reason of these emotions and you will understand if there really was something you need to worry about.
Don't tell emotional people to calm down, it won't work anyway. You will only upset or even offend the person who overreacted to something.
